After I got to kill the dragon with my friend, we both entered the end portal to exit to the overworld. From his part the game continued successfully, he was the host. From my part, as soon as I entered my game crashed. I tried to rejoin but the game continued to crash. I later decided to change all my graphics options to the lowest. Now I'm able to join but unable to skip the credits. After the credits end, I'm left with a black screen and nothing else happens.

In order to replicate:
1- In a multiplayer game, as a player that is not the host, use the end portal to exit the end.
